This game is one of the best action adventure games I've played in years. It's definitely the best Batman and probably superhero themed games ever released. Great plot line with interesting settings. The game requires some thoughts and it's not those beat'em ups or mindless run and gun games that you see now-a-days. I see that there's a reviewer that was frustrated with precision controls, but the fact is, this game was never meant to require precision controls like first person shooting games like Counterstrike or Battlefield: Bad Company 2. This game is great for those people who just wants to be Batman and live through his adventures.
I finished the campaign with my trusty XBOX 360 Controller for PC but I've also played the game using the traditional keyboard and mouse schemes. Since the game was originally written for consoles, I of course stuck with the control schemes the designers originally had in mind, and it works great. I would also give kudos to the team for having quite control translation to the traditional keyboard and mouse layout. Unfortunately, I didn't feel like button mashing my keyboard to the point it feels like my keyboard's going to fall apart nor do I feel like killing my mouse, so I stuck to mainly the controller.
If you've been looking for an excellent action adventure game, look no further than this game. Personally, I'm not into comics at all and my exposure to Batman is through the movies and this game. The only reason why I bought this game was because of all the praise it received and I didn't feel like getting another shooter game.
